摘要： A computing system and methods are provided for georeferencing stabilization. An exemplary method includes: obtaining a video stream capturing an area from a camera of a drone, where the video stream includes a plurality of frames, each including a field of view of the image capturing device and metadata of the image capturing device when the frame is captured; constructing a geographic (geo) lattice for the field of view in each of the plurality of frames, the geo lattice comprises a plurality of points, each being associated with raw coordinates determined based on the corresponding metadata; and building a lattice map with stabilized geo coordinates by (1) aligning the frames, (2) averaging the raw geo coordinates for given intersection points, and (3) building the lattice map based on the averaged geo coordinates of the intersection points.

摘要： Mappings are determined between viewpoints of an object and an object model representing the object. Each mapping identifies a location on the object model corresponding with a portion of the object captured in one of the viewpoints. Tags for the object model are created based on the mappings, where each tag links one of the viewpoints to one of the locations on the object model. A user interface that includes the object model and the tags is provided for presentation on a display screen in a user interface. One of the viewpoints is presented in the user interface when the corresponding tag is selected in the object model.

摘要： An example disclosed method includes (i) transmitting a first point cloud to a client, wherein the first point cloud corresponds to a reference point cloud, (ii) receiving a second point cloud, and (iii) hierarchically determining changes in the second point cloud from the reference point cloud, wherein hierarchically determining the changes includes (a) identifying first areas in the second point cloud that have changed from the reference point cloud, and (b) for a first area having a highest priority, determining a first rigid 3D transformation that approximates a first change from the reference point cloud, and if the first rigid 3D transformation cannot be determined, further determining first points to be used to modify the reference point cloud, wherein the first points are representative of the first change.

摘要： A method, and corresponding apparatus, for identifying a feature in an image comprises determining a plurality of characteristic values for each pixel or group of pixels within the image, and determining a confidence value for a target area of the image on the basis of the plurality of characteristic values of the pixels within the target area. Each of the plurality of characteristic values relates to a different characteristic of the feature. The confidence value is indicative of whether the feature is represented by the target area of the image.

摘要： Systems and methods for detecting cracks in a surface by analyzing a video, including an full-HD video, of the surface. The video contains successive frames, wherein individual frames of overlapping consecutive pairs of the successive frames have overlapping areas and a crack that appears in a first individual frame of a consecutive pair of the successive frames also appears in at least a second individual frame of the consecutive pair. A fully convolutional network (FCN) architecture implemented on a processing device is then used to analyze at least some of the individual frames of the video to generate crack score maps for the individual frames, and a parametric data fusion scheme implemented on a processing device is used to fuse crack scores of the crack score maps of the individual frames to identify cracks in the individual frames.
